"EU has extended economic sanctions against Russia until 31 January 2016, with a view to complete implementation of (the) Minsk agreement," an EU spokeswoman said in a tweeted message.

The 28-nation bloc initially imposed travel bans and asset freezes against Russian and Ukrainian figures for their part in the crisis but reacted sharply after Malaysia Airlines flight MH17 was shot down in July over territory held by pro-Moscow rebels.

Brussels hit Russia's banking, oil and defence sectors hard and, along with the United States, has warned more sanctions could follow unless Moscow lives up to its Minsk commitments to withdraw support for the rebels and use its influence with them to implement the accord.

In March, EU leaders agreed in principle to roll the sanctions over by linking them directly to the ceasefire brokered by France and Germany in Minsk that runs to December this year.

The ceasefire has largely held since then but Kiev and the rebels swap charges daily over breaches and observers reported a sharp pick up in fighting earlier this month in a conflict which has claimed more than 6,400 lives and destroyed much of eastern Ukraine.

The foreign ministers of France, Germany, Ukraine and Russia are due to meet in Paris on Tuesday to review the situation.

The Ukraine crisis has plunged EU and US ties with Russia into the deep freeze, with some of the exchanges reminiscent of Cold War tensions.
